Answer:
(c) system.exist(1);
Step-by-step explanation:
system.exist(1); is used for the termination of the program here both option c and d should be correct but in option d there is exit(0) and zero indicates return means program will return but besides zero if there is any non zero number then program will not return and in option c there is a non zero number which means program will not return so option c system.exist(1); will be the correct option for the termination of program
